    OMAPDSS: DISPC: remove OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES · 7a16360d

    DISPC can drive data lines either on rising or falling pixel clock edge,
    which can be configured by the user.
    
    Sync lines can also be driven on rising or falling pixel clock edge, but
    additionally the HW can be configured to drive the sync lines on
    opposite clock edge from the data lines.
    
    This opposite edge setting does not make any sense, as the same effect
    can be achieved by just setting the sync lines to be driven on the other
    edge compared to the data lines. It feels like some kind of backward
    compatibility option, even if all DSS versions seem to have the same
    implementation.
    
    To simplify the code and configuration of the signals, and to make the
    dispc timings more compatible with what is used on other platforms,
    let's just remove the whole opposite-edge support.
    
    The drivers that used OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES setting are
    changed so that they use the opposite setting from the data edge.
